Multiple Tesla Cybertruck owners share that their truck’s stainless steel has been rusted and corroded after exposure to a magnet. One owner specifically details the effects magnets have had on his Cybertruck’s stainless steel surface.
There are different types and grades of stainless steel for different purposes. Generally speaking though, magnetic stainless steel will rust more easily than non-magnetic.
Yep. 17-4 stainless steel (which is magnetic and is fairly widely used) is just as corrosion resistant as 304 stainless while also being stronger and hardenable. It’s not as resistant as things like 316 (non-magnetic, the gold standard for low cost, low strength corrosion resistance), 2205 Duplex (magnetic, more expensive, more resistant, stronger than 316), or Cronidur 30 (magnetic, fairly exotic, ridiculouly strong and corrosion resistant in many environments), but it’s pretty good.
I’ve no idea if this is what the stupid truck is using, but there are some pretty damn good magnetic stainless steels out there.
EDIT: They’re using 301 stainless steel. It’s not magnetic under normal circumstances, but becomes magnetic when cold worked. It is not a very corrosion resistant stainless lol. Motherfucker should have used 316 (or better yet, 316L) like the DeLorean did.
EDIT: I dunno if the DeLorean actually used 316. There’s a lot of conflicting information out there. I am now giving up.
How shitty is the stainless steel that allows a fucking magnet to stick to it to begin with?
